2. Look Inside the Eye
Color vision can be defined by what
kind of color-detecting equipment
exists inside the eye of a human
or non-human animal. Some
species see no colors, some see
a few colors, some see all colors,
and some see colors that are not
visible to the typical human eye.
The color-detecting equipment inside
an eye is called a "cone."
(The rods are for night vision.)
4. RGB
The additive reproduction process usually ses red, green and bluelight
to produce the other colors. Combining one of these additive primary
colors with another in equal amounts produces the additive secondary
colors cyan, magenta, and yellow. Combining all three primary lights
(colors) in equal intensities produces white
5. In painting and other visual arts, two-dimensional color wheels or three-dimensional color
solids are used as tools to teach beginners the essential relationships between colors.
The organization of colors in a particular color model depends on the purpose of that
model: some models show relationships based on Human color perception, whereas
others are based on the color mixing properties of a particular medium such as a
computer display or set of paints.
6. Tints, Shades, and Tones
These terms are often used incorrectly, although they describe fairly simple color concepts. If a color
is made lighter by adding white, the result is called a tint. If black is added, the darker version is
called a shade. And if gray is added, the result is a different tone.
Tints - adding white to a pure hue :
Shades - adding black to a pure hue:
Tones - adding gray to a pure hue:

8. Warm and cool colors
The color circle can be divided into warm and cool colors.
Warm colors are vivid and energetic, and tend to advance in space.
Cool colors give an impression of calm, and create a soothing
impression.
White, black and gray are considered to be neutral.
9. Some Formulas for Color Harmony
There are many theories for harmony. The following illustrations and descriptions
present some basic formulas .
A color scheme based on analogous colors
Analogous colors are any three colors which are side by side on a 12 part
color wheel, such as yellow-green, yellow, and yellow-orange. Usually one
of the three colors predominates.
A color scheme based on complementary colors
Complementary colors are any two colors which are directly opposite each
other, such as red and green and red-purple and yellow-green. In the
illustration above, there are several variations of yellow-green in the leaves and
several variations of red-purple in the orchid. These opposing colors create
maximum contrast and maximum stability.
10. A color scheme based on nature
Nature provides a perfect departure point for color harmony. In the illustration
above, red yellow and green create a harmonious design, regardless of
whether this combination fits into a technical formula for color harmony.
Color Context
How color behaves in relation to other colors and shapes is a complex area of
color theory. Compare the contrast effects of different color backgrounds for
the same red square.
Red appears more brilliant against a black background and somewhat duller
against the white background. In contrast with orange, the red appears lifeless;
in contrast with blue-green, it exhibits brilliance. Notice that the red square
appears larger on black than on other background colors.
11. • Different readings of the same color
If your computer has sufficient color stability and gamma correction (link to Color Blind
Computers) you will see that the small purple rectangle on the left appears to have a
red-purple tinge when compared to the small purple rectangle on the right. They are
both the same color as seen in the illustration below. This demonstrates how three
colors can be perceived as four colors.
Observing the effects colors have on each other is the starting point for understanding
the relativity of color. The relationship of values, saturations and the warmth or coolness
of respective hues can cause noticeable differences in our perception of color.
13. Color harmony and color meaning
It has been suggested that "Colors seen together to produce a pleasing
affective response are said to be in harmony".However, color
harmony is a somewhat misleading notion in that responses to color
can be influenced by a range of different factors including individual
differences (age, gender, etc.); cultural and social differences; as
well as contextual, temporal and perceptual factors.
Activity 1
Search in internet .Choose one color and explain its meaning. Put differents axamples of
works of art and explain them.
Power point presentation in 3 sheets.
Activity 2
Choose two or three geometrical shapes. Draw them with a graphite pencil. Use
temperas to paint them.
